IMPROVEMENT IN MACHINES FOR CUTTING FAN-LEAVES.

Specification forming part of Letters Patent No. 164,838, dated June2'3, 1875; application filed April, 9, 1875.

To all whom it may concern:

Mount Vernon, in the county of Westchestcr and State of New York, haveinven ted a certain new and useful Improvement in Machines for CuttingFan-Leaves, of which the following is a specification:

This invention is illustrated in the accompanying drawing, in which-Figure 1 shows a longitudinal section. Fig. 2 is an end elevation,showing the knife-carriage;Fig. 3 is a transverse section Fig. at is anend elevation, showing the feed mechanism.

Similar letters indicate corresponding parts.

This invention relates to a machine designed mainly for cutting leaves,the construction of fans, and consists in the combination of areciprocatin g knife and its carriage,a spring-clamp, and anintermittent feed mechanism, the spring-clamp being capable of areciprocating motion, and allowing of an intermittent feeding ofmaterial under the knife, whereby I obtain a machine adapted for cuttingleaves of uniform thickness. The im termittent feed mechanism isadjustable as to its extent of motion, and by this arrangement leaves ofany desired thickness can be cut by my machine.

The springclamp receives a reciprocating motion through the medium ofthe knife-carriage, being provided with a lateral projection with whichthe carriage comes in contact in its ascent, and through the action ofits springs, a tendency to hold it in contact with the material to beout. The intermittent feed mechanism is constructed of a feeder, mountedon a screw-shaft, which is combined with driving-gear and aratchet-wheel that receives an intermittent motion through a pawlattached to a vibrating lever, which is connected eccentrically to adriving-wheel.

' The vibrating lever is connected to the driving-wheel by means of aset-screw, which is adjusted in a radial groove on the wheel, wherebythe lever is adapted to be connected at any distance from the center ofthe wheel, in order to regulate the extent of feed motion.

In the drawing, the letter A designates the bed-plate of my machine,which is supported mounted an eccentric or cam, such as are used in byframe-pieces B B, at or near the respective ends, and to one end ofwhich is secured a delivery-board, O. The bed-plate as well as thedelivery-board are inclined, in transverse section, and the bed-plate isprovided with a rib, a, that forms both a guide and stop for thematerial laid thereon. D designates the knifecarriage, which is locatedat or near one end of the machine, and to which is fastened a' suitableknife, E. The vertical edges of the knifecarriage l) are fitted in waysF, formed on opposite sides of the approximate frame-piece B, and inwhich ways the carriage is guided in its reciprocating movement. Gdesignates the driving-shaft of my machine, on which is H, which worksin a slot, I, Fig. 2, formed on the lower part of the knife-carriage.The eccentric is preferably arranged in abox, J, that is fitted to theslot I. When a revolving motion is imparted to the driving shaft, andthrough it to the eccentric, the latter imparts a reciprocating motionto the knife-carriage and knife. K designates a log of wood or othermaterial, which I have shown as resting on the bed-plate A, and as.

being fed under the knife.

The log is held in place during the opera tion of cutting by means of aclamp, L, which acts under the influence of springs M, Fig. 3. Thesprings M are made of wire, which is coiled on vertical rods N, fastenedto the clamp, one end of the springs bearing against or being fastenedto the rods, while the other end bears against lugs b, of theapproximate frame-piece B, as seen in Fig. 3. This spring. clamp L isattached to a stock, 0, which has a lateral projection, P, extending inthe direction of the knife-carriage. Through the pro jection 1? passes ascrew, 0, which is so located that it is in a vertical line with theknife carriage D, and when the carriage, in its reciprocating movement,ascends, it strikes against the screw and thus carries the clamp .L withit against the action of the springs M,

while when the carriage descends the springs causethe clamp to return toits normal position. The relative position of the knife-carriage andclamp arev such that the clamp returns to its contact with the log Kbefore the knife begins to out, so that the log is firmly held duringthis operation. I

Between the screw P and the clamp is interposed a spring, d, of'india-rubber or other suitable material, for the purpose ofcounteracting any irregularity in the surface of the log K. The clamp isguided in the reciproeating movement imparted to it, as beforedescribed, by its rods N, sliding in the lugs b. It is obvious that, asoften as the clamp L rises, the log K may be fed or moved forward underthe knife, in order to cut therefrom repeatedly. This movement iseffected by means of the feeder Q, which traverses a slot in thebed-plate A, and bears against the tail end of the log K, being arrangedto move the log at uniform intervals, as well as to uniform distances,varying with the thickness of leaves to be cut. The feeder Q is made inthe form of a nut, and is mounted on a shaft, R, which is provided witha screw-thread for nearly the whole of its length. The feeder ispreferably divided into two parts, which can be taken apart, in orderthat the feeder may be moved from one to the other end of the shaft.

The outer end of the shaft R contains a gearwheel, S, which connects bya pinion, d, with a second gear-wheel, T, shown in Fig. 4 in dottedoutline. The arbor of the wheel T has its bearing in the approximateframe-piece B, and carries a ratchet-wheel, U, together with one arm ofan elbow-lever, V, the other arm of which is connected to an eccentricportion of the driving-wheel WV. To the elbow-lever V is pivoted a pawl,e, and at such a portion thereof that it is adapted to engage with theteeth of the ratchet-wheel. The driving-wheel W is mounted on thedriving-shaft G, and

when this wheel is given a revolving motion,

the lever V is vibrated and the pawl 12 successively engages the severalteeth of the ratchet-wheel U. By these means the ratchetwheel isintermittingly moved to the extent 'of one of its teeth, which motion isthence communicated to the driving-gear and to the 'eeder Q. Theratchet-wheel U is provided with a series of teeth, t, of uniformlength,

and two t the length of which is nearly equal to the two of the teeth25.

The throw of the pawl e is just equal to the length of the teeth t sothat for each throw it takes only one of the teeth t, or one of theteeth t By the long teeth t the block is fed a sufficient distance forthe covers of a fan, while the feed motion produced by the short teethis for the fasteners. The number of teeth on the ratchet-wheelcorresponds to the number of leaves required for each fan.

The pinion d is supported by a lever, Y, pivoted at f to the frame-pieceB, and which moves within a guide-plate g, having a slot, h,

in which moves a set-screw, 1', connected with the lever. By thisarrangement the lever Y can be adjusted and retained in any position,and so as to connect or disconnect the drivinggear by bringing thepinion d in or out of gear.

The elbow-lever V carries a set-screw, j, by means of which it isconnected to the side of the driving-wheel W, the set-screw catching ina' groove, k, (or in a slot,) formed in the wheel. The object of thisarrangement is to allow of connecting the lever to any portion of thewheel W that is to say, at any distance from the center of the wheel-andthereby the extent of the motion of the lever and of the entire feedmotion maybe regulated so as to out any desired thickness of leaf.

What I claim as new, and desire to secure by Letters Patent, is

l. The combination of an adjustable intermittent feed mechanism, areciprocating knifecarriage, a spring-clamp for holding the work,

the whole being constructed for operation, as

herein shown and described.

2. The combination, with the reciprocating knife-carriage and springclamp L, of the feed mechanism, consisting of the feeder Q, screwshaftR, driving gear S T, ratchet-wheel U, eccentric V, and pawl e,substantially as and for the purpose described.

In testimony that I claim the foregoing I have hereunto set my hand andseal this 3d day of April, 1875.
